Recurrent Candida esophagitis in an Immunocompetent Patient

Abstract: Introduction Candida esophagitis (CE) is commonly reported in patients with impaired cell-mediated immunodeficiency, such as patients with AIDS and transplants, but rarely reported in immunocompetent adults. We report a case of recurrent Candida albicans esophagitis in a patient without traditional risk factors. Case A 72-year-old female with past medical history of insulin-requiring diabetes mellitus and mild asthma presented in September 2008 with progressive odynophagia and retrosternal chest discomfort for several months. The patient had lost five pounds but otherwise denied fevers, chills or other complaints. She had not taken systemic or inhaled corticosteroids or antibiotics in several years. Upon examination, she was well appearing, her mucous membranes were clear, there was no lymphadenopathy and her abdominal examination was within normal limits. Her CBC revealed a normal leukocyte count, hemoglobin 10.2 g/dL, albumin 3.1 g/dL and HgbA1c 7.7 %. HIV antibody An esophagoduodenoscopy (EGD) was performed and revealed white exudate covering most of the esophagus. Esophageal manometry also revealed esophageal motility disorder. The patient was treated with a 10-day course of oral fluconazole with clinical resolution. Her symptoms recurred in May 2010 and repeat EGD again was consistent with CE both on appearance and in the biopsy. An HIV antibody was negative and quantitative serum immunoglobulins were within normal limits. The patient was treated again successfully with two weeks of oral fluconazole but she relapsed two weeks after discontinuing therapy. Over the last year, the patient has required suppressive fluconazole 100 mg daily to prevent further relapses. In April 2011, she presented again with recurrent esophageal symptoms and repeat EGD again demonstrated findings consistent with CE. An esophageal biopsy was sent for fungal culture that grew C. albicans that demonstrated a fluconazole minimum inhibitory concentration of 16 g/mL (susceptible < 8). The patient is now being treated with a fluconazole dose of 200 mg daily pending further evaluation. Discussion This case illustrates that idiopathic CE can present in patients without traditional risk factors. Risk factors that have been identified among non-HIV and non-transplant patients include recent antibiotics, systemic or inhaled corticosteroids, diabetes mellitus, acid suppressive therapy and esophageal motility disorders. Our patient is unique with respect to the multiple recurrences and development of increasing azole resistance that are typically seen in patients with AIDS-related CE.
